	ExecutionTimeout:        DefaultExecutionTimeout,

Types ¶

type Config ¶

type Config struct {
	RollCallTimeout         time.Duration  // How long do we wait for roll call responses.
	ExecutionTimeout        time.Duration  // How long does the head node wait for worker nodes to send their execution results.
	ClusterFormationTimeout time.Duration  // How long do we wait for the nodes to form a cluster for an execution.
	DefaultConsensus        consensus.Type // Default consensus algorithm to use.
}

Config represents the Node configuration.

func (Config) Valid ¶

func (c Config) Valid() error

type HeadNode ¶

type HeadNode struct {
	node.Core
	// contains filtered or unexported fields
}

func New ¶

func New(core node.Core, options ...Option) (*HeadNode, error)

func (*HeadNode) ExecuteFunction ¶

func (h *HeadNode) ExecuteFunction(ctx context.Context, req execute.Request, subgroup string) (codes.Code, string, execute.ResultMap, execute.Cluster, error)

ExecuteFunction can be used to start function execution. At the moment this is used by the API server to start execution on the head node.

func (*HeadNode) ExecutionResult ¶

func (h *HeadNode) ExecutionResult(id string) (execute.ResultMap, bool)

ExecutionResult fetches the execution result from the node cache.

func (*HeadNode) PublishFunctionInstall ¶

func (h *HeadNode) PublishFunctionInstall(ctx context.Context, uri string, cid string, subgroup string) error

PublishFunctionInstall publishes a function install message.

func (*HeadNode) Run ¶

func (h *HeadNode) Run(ctx context.Context) error

type Option ¶

type Option func(*Config)

Option can be used to set Node configuration options.
